MARKER FOR PRES SED STEEL.

SPECIFICATION forming part of Letters Patent No. 724,163, dated March31, 1903.

Application filed October 23,1902. Serial No. 128,375. (No model.)

To all whom it may concern:

Be it known thatI, NEWELL P. CoWELL, a citizen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMarkers for Pressed Steel, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in markersor punchers for pressed-steel work, and has for its object to provide amarker which may be either employed to automatically mark or punch thespirit of myinvention. The function of these work being shaped oroperated by hand.

The invention contemplates the provision of a marker or puncher which isarrangedwithin one of the walls of the die in any desired position,whereby asthe article is being. shaped one or more marks are producedthereon or one or more holes punched therein, the marks indicating theplaces which are thereafter to be punched or drilled to prowithina dieadjacent. to one side of the dieduce the bolt or rivet openings.

Heretofore when the article was produced it had to subsequently be boredor, in other Words, provided with openings to receive the securingmeans, the shaped article being first.

cooled and the positions for the bol -openings afterward determined. Thepresent invention produces the marks for bolt-openings," as

heretofore stated, while the article is being shaped, and it willtherefore be apparent that when the article comes from the die it is incondition to be punched or drilled and the openings in each instancewill be found to be true. By simply making the punchers which producethe marks of a length andsize conforming to the hole it is desired toproduce the punchers maybe employed for forming the holes, thusdispensing with any subsequent punching or drilling.

In describing the invention indetail reference is had to theaccompanyingdrawings, formingapart of this specificatiomand wherein likenumerals of reference indicate like parts throughout f the severalviews, in which- I Figure 1 is a viewin perspective of a portion of adie embodying the present invention. Fig. 2 is a vertical sectional viewof my improved marker or puncher. Fig. 3 is a front elevation ofthesame. Fig. 4 is a view taken on the line 4. 4 of Fig. 2. Fig. 5 is asection taken on the line 5 5 of Fig. 2.

' Fig. 6 is a perspective view of the plunger.

In the drawings the reference numeral 1 indicates a suitable die inwhich is arranged an approximately rectangular casing 2, said casingbeing provided in one of its walls with aseries of apertures 2',arranged in vertical alinement. Although in the'drawingsI have shown butthree openings, it will be obvious that I may employ in lieu thereof agreater or less number without departing from the casing and provide thesame in its one wall with an elongated slot 5, which registers with theopening of the said casing 2. The casing 3 is hollow and is provided onits rear wall with 'an inclined shoulder 6, which is ar-.

ranged at the upper end of the centrally-arranged thickened portion 17,which portion extends to a point adjacent to the lower end of thecasing. This rear wall also carries inclined shoulders 6 6 near thelower end,

adapted to be engaged by inclined shoulders on the plunger, as will belater described.

8 indicates a laterally-moving plate arranged within the casingand-havingits lower edge in engagement with the seat 9, on which thesaid plate moves. 10 indicates a series of markers or punchers which areremovably secured to the said plate and which are adapted during ther'novementof theplate to project through the elongated slot of thecasing and the apertures of the rectangularcasing 2 and engage thearticle being shaped. In the drawings the markers or punchers are shownsupported in position by means of screw-threaded bolts. It will beobvious, however, if I so desire, that I may employ other means forsecuring the same in position, and

IOO

I vary the number of the same to correspond with the number of openingsin the die casing 2 as they are varied; also, that by making thepunchers or markers of a su tlicient length and of the desired size theymay be employed for producing the holes, thus dispensing with any afterdrilling or punching.

11 indicates a plunger arranged between the plate 8 and the thickenedportion 7 of the casing, said plunger provided adjacentits upperend onits rear face with an inclined shoulder 6, adapted to engage with theinclined shoulder 6. This plunger normally has its upper end projectingthrough an opening 12 in the top of its casing and is capable of movingin a vertical plane. The plunger is also provided on its rear face nearthe lower end with inclined shoulders 13, which engage the inclinedsurfaces of the shoulders 6', spaced apart and formed integral withtheinner face of the rear wall of the casing adjacent its lower end.

15 15 indicate a pai rofdownwardly-extending hooks carried by the innerface of the sliding plate 8, which hooks straddle the plunger and engagewith studs 16, arranged on opposite sides and formed integral with saidplunger. The plunger is provided in its front face with a verticalgroove 11 to receive the heads of the screws which secure the markers orpunchers 10 to the plate 8, and on its rear face directly above theshoulders 13 the plunger carries a lug 12, between which and the bottomof the casing is arranged a spring 17 for returning the plunger to itselevated position.

From the foregoing description it will be apparent that when the plungeris depressed. the inclined shoulders t3 and 13, engaging the inclinedshoulders 6 and 6, will impart a sliding lateral movement to the saidplunger, which movement is communicated to the sliding plate andconsequently the markers or punchers are forced outward through thecasing and into the article being shaped. When the pressure is relievedfrom the plunger, the

spring 17 will force the said plunger into its normal position, and asthe said plate 8 is connected to the plunger through the me-. dium ofthe hooks 15 the plate will be withdrawn from engagement with the die.

In practice if a two-part die is employed it will be obvious that theupper section ofthe die bearing upon the upper end of the plunger willforce the same downwardly and retain the same in this depressed positionuntil the said upper section is moved, thereby producing the desiredresults. If, however, the upper die-section is not employed, the upperend of the said plunger can be depressed in any desired manneras, forinstance, by being struck by a hammer.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
